"Sons of Anarchy" is one of the most successful shows of the recent era. Fans around the world are anticipating season 6 with tremendous fervor and series creator Kurt Sutter has decided to tease them with new information on the show's main characters and the ending during an interview with Zap2It.

Regarding ever-violent protagonist Jax (Charlie Hunnam), Sutter revealed that the death of his best friend Opie Winston in Season 5 drives him.

"Opie set himself up, knowing where it was all going to a certain extent. And him sacrificing himself for the club, for Jax to walk away would be dishonoring his memory," Sutter revealed in the interview. "That's what I'm talking about when I say the ghost of Opie is living in Jax, in at least the first half of the season, and is sort of motivating him to ... not necessarily go rogue, but perhaps pushing him down this path where he may be leaping before he looks."

He also talked about Ron Perlman's aversion to his role of Clay. The character has lost his power, family, and friends and is in an increasingly isolated state of mind; this has made Perlman incredibly uncomfortable.

"Yeah, you know it's interesting. Actors always sort of tend to experience what their characters are going through," said Sutter. "When you've been part of something so long, and are so committed to it ... It's so ironic because I think a lot of what Ron is feeling, in terms of what's going on with Clay, is really what Clay is feeling."

He also offered some detail on the highly anticipated finale and noted that lovers of happy endings may not be completely satisfied.

"You know, here's how I describe all this: It's a heavy world, it's a dark world but as heavy and violent as it is, I like to think that ultimately there is some sense of hope. So that it's sad and heavy, but there is always some sense of hope," he said. "Will it be a happy ending? No, but I do think that there will be something hopeful about the way it ends.

Season 6 of "Sons of Anarchy" is slated to premiere on Tuesday, September 10 at 10 p.m. on FX.
